Abstract: A layered panel structure featuring a first layer formed of non-thermoformable material, having opposite faces, a thickness T as measured between its opposite faces, and an effective layer density d, and a second layer formed of thermoformable material having opposite faces, with one face in the second layer being thermally bonded to one face in the first layer, and with the second layer having a thickness t, as measured between its opposite faces which is smaller than T, and an effective layer density D which is greater than d. The thermal bond between the layers is formed, during thermoforming of the panel structure, by a melt and flow of resin contained in the thermoformable layer material.

Abstract: A method utilizing a spray instrumentality for spray-applying to a target surface in a target zone a defined, composite-material layer which is to play a role in defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character.

Abstract: A bulk, generally elastomeric and pliable, layered mat formed to permit selective trimming into size-chosen mat trims/tiles, each of which is structured to perform as a self-puncture(wound)-sealing, defined-liquid-reactive, anti-puncture-leakage coating element applicable bondedly to the outside surface of a selected wall in a container holding the defined-liquid. The mat is made by preparing it as a generally elastomeric, pliable, layered arrangement of coatings formed of self-puncture-healing, defined-liquid-reactive, anti-puncture-leakage material, or materials; and is applied for use in relation to a selected container wall by (1) trimming, from the prepared mat, one or more trims/tiles shaped for specific use on the outside surface of that wall; and (2) applying and surface-bonding the one or more trims/tiles to the outside surface of the selected wall.

Abstract: A hearing protection device such as a headset or headphone having ear cups is provided with ear seals that incorporate an acoustic barrier for attenuating external noise levels in the interior of the ear cups. The ear seals completely encircle the wearer's ear and use cushioning material into which the acoustic barrier is embedded or otherwise associated. The acoustic barrier comprises a strip or flange of material that is denser than the cushioning material and provides enhanced cross sectional attenuation. The acoustic barrier blocks external noise to reduce the level of noise within the internal cell of the ear cup.

Abstract: Barrier structure for furnishing, selectively and variously, penetration and fire-threat protection on the outside surface of a target structure. The barrier structure includes a high-elastomeric coating having an inner face bonded to such a surface, an exposed outer face, and, within this coating, at least one elastomeric layer region extending to the outer face, and containing an embedded distribution of intumescence elements. Basic variations of this structure include (a) an additional layer region which is formed with elastomeric-material including an embedded distribution of liquid-imbiber beads, and (b) an additional layer region which is formed purely of elastomeric material. The elastomeric material employed, and the embedded liquid-imbiber beads where included, react to liquid petroleum-based substances (1) to imbibe such liquid, (2) to swell in size as a result of such imbibing, and (3) to coagulate into a sticky mass.

The method includes the steps of (a) selecting starter materials having known, respective, nominal density and thickness characteristics, (b) creating an unconsolidated stack of such materials to have a combined-material density D1 and thickness T1, (c) applying heat and pressure to that stack, and (d) thereby consolidating and compressing the stack to produce the desired, finished structural panel possessing an overall, combined-material density D2 and thickness T2.

This structure implements a method for minimizing, in a solid-fuel rocket, heat damage to the wall of a solid-fuel container during burning of contained solid fuel including the steps of (a) producing dual-interface, continuous-presence, heat-insulative barriering in the zone existing between the container and burning fuel, with such barriering being characterized by (1) interfacially following any heat-produced deformations in the container wall, and (2) interfacially confronting the burning fuel with a tendency for intumescence-driven barrier-thickening.

Abstract: Spray-formed, anti-burst, leak-self-sealing coating structure applicable to the outside surface of a fuel container, and an associated application methodology. In an operative condition relative to such a surface, the coating structure includes (a) a solid, continuous-phase body of fuel-reactive, high-elastomeric material in the form of an expanse having an inner side applied to such a surface, and a spaced, outer side, (b) a field of distributed, fuel-reactive, fuel-imbiber beads embedded in and throughout the expanse of said body, generally spaced from, and centrally between, the body's inner and outer sides, but exposed to neither such side, and (c) an anti-burst fabric web having meshes formed by elongate, stretch-resistant fibers extending generally centrally within and throughout bead field. Meshes in the fabric web, and beads in the bead field, are relatively sized appropriately to permit the ready mesh-through-passage of beads during spray-formation of the coating structure.

The coating structure, in operative condition with respect to such a hull portion, includes a body of continuous-phase, non-water-reactive, high-elastomeric-material, and, embedded within that body, in an initially shrouded and non-exposed condition guarded nominally against any contact with external water, a distribution of water-reactive, water-imbiber beads.

Abstract: A method for establishing a sprayable stream of composite material for spray-applying to a target surface to create thereon a defined composite-material coating designed for defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character, where the target surface is on a side of that wall.

Abstract: An embedded-object composite product including a solid-state mass of PET, an object embedded in the PET material mass, and a zone possessing a continuous material-density gradient in the PET material mass, with more-dense PET material residing closely adjacent the embedded object, and less-dense PET material residing more distant from that object. This product is produced effectively by non-destructively heating the PET mass from its solid state to allow it to flow as a liquid, by then pressing the object into the heated PET mass to perform object embedment and to create a declining PET-material density in the region adjacent, and progressing from adjacent, the embedded object, and by thereafter cooling the mass to re-solidify it.
